It's fine for a seinen since it seems it's trying to be more grounded and about finding personal fulfilment rather than world-altering stakes.
Honestly I find the oddest part of the premise is how even though it seems to take place around the 2010s or 2020s it also doesn't apparently address Heisei series? I get Tojima himself being plausibly a purist for Showa but with the premise of people living out Kamen Rider fantasies in a modern Japan I'd expect to see someone like a Kuuga or a group of bros cosplaying the Imagin sooner than a Tackle or Riderman. This shot I'd expect to see an Ex-Aid or Build mask on the stand if it's 2018.
If it was set in the late 90s I think that the concept still makes sense but avoids that problem. I get that the author specifically wants it to be Showa-focused but it should be set before Heisei if Heisei isn't going to appear.
